Question

If p(1,2), q(4,6), r(5,7) and s(a,b) are the vertices of parellelogram pqrs, then a=?,b=?

Answer 1

Answer:

Step-by-step explanation:

mid point of pq = mid point of rs

1+4/2 ; 2+6/2 = 5+a/2 ; 7+ b/2

5/2 ; 4 = 5+a/2 ; 7+b/2

Comparing coordinates on both sides

5/2 = 5+a/2 & 4 = 7+b/2

5 = 5+a & 8=7+b

a = 0 & b = 1

therefore a = 0; b = 1
